It worked (after testing an ungodly number of combinations, see supp.)! Three human-derived modules, PHD3, SLY-VHL, HIFODD, form a fully functional O2-dependent proteolysis system in Arabidopsis. We could degrade reporters, TFs, even fluorescent proteins, all reversibly controlled by oxygen levels.

Very nice story! Congrats everyone 🎊🥳

PNAS: A secreted citrus protease cleaves an outer membrane protein of the Huanglongbing pathogen (2026) Plants secrete a variety of proteases as a defense response during infection by microbial pathogens. However, the relationship between their catalytic activities and antimicrobial functions remains largely unknown. Particularly, few biologically relevant substrates of these proteases have been identified. Huanglongbing (HLB) has been a major threat to the citrus industry worldwide. The HLB-associated bacterium, "Candidatus Liberibacter asiaticus" (Las), was previously shown to deploy an inhibitor of papain-like cysteine proteases (PLCPs) to promote disease in citrus. In this study, we identified an outer membrane protein (OMP) of Las, LasOMP1, as a substrate of the citrus PLCP CsRD21a. LasOMP1 is one of the most highly expressed genes in Las. CsRD21a cleaves LasOMP1 and produces cleaved peptide products, which could be detected in vitro and in HLB-diseased citrus plants. We found that CsRD21a targets the N-terminal portion of LasOMP1, potentially at an extracellular loop region. Importantly, transgenic sweet orange overexpressing CsRD21a showed reduced Las populations and improved plant growth, highlighting that engineering this protease is a promising strategy to enhance HLB resistance in citrus. Together, our work reveals a pathogen-derived substrate of plant PLCPs and suggests bacterial OMPs may be direct targets of plant defense.

Comparative proteomic profiling of receptor kinase signaling reveals key trafficking components enforcing plant stomatal development Proteomic mapping uncovers endocytosis adaptors that drive receptor internalization for robust stomatal development.

Published! From a proteomic atlas of the ERECTA signaling network, we show that receptor kinase endocytosis is essential for proper stomatal patterning. Congrats, Pengfei, @edwardmarcotte.bsky.social, @hhmi-science.bsky.social, @texasscience.bsky.social & co-authors!

Excited to share our latest preprint. Arabidopsis thaliana has been the leading model for plant genetics - but most of what we know comes from growth chambers.
Can this model also help us understand how climate shapes plants in the wild and reveal gene functions under real environmental variability?

Announcing the publication of TAIR12: Consult the fully reannotated genome on the European Nucleotide Archive - Phoenix Bioinformatics TAIR (The Arabidopsis Information Resource), together with our nonprofit host Phoenix Bioinformatics, is pleased to announce the public release of TAIR12

🎉📣 #TAIR12, the latest reannotation of the Arabidopsis thaliana genome, is now available under accession number PRJEB100887 on ENA and NCBI!

Thank you all the volunteer researchers whose hard work has made this possible!

English is the dominant language of science. Does this help us share knowledge? Or does it further exclude the already excluded?

This webinar looks back at the colonial past of science communication and how we can better embrace multilingual science: buff.ly/5f2uPQi

Like, the storyline's format, the size of preliminary data, how to explain objectives/work packages, and what adjectives were most common

I'm super curious about how the writing style then compares to what we do now. If you've got an old proposal you'd be willing to share, or even just some insights into the typical style from that era, I'd love to hear about it! Drop a comment or send me a DM. 🌱 #writing #proposal

Just submitted my first PI grant proposal – what a wild ride! It got me wondering about something specific: for those of you in plant science, what did grant proposals look like back in the late '90s or early 2000s? #writing #proposal

A PhD position (initially 3 years) is available in our laboratory in the Center for Plant Molecular Biology (ZMBP), at the University of Tübingen (Germany).

Scheme how genetically encoded biosensors can shine light on plant metabolism. Intrinsic sensors bind their analyte directly, extrensic sensors require a sensing domain fused to one, or more, fluorescent proteins. In paraplexing experiments, multiple sensors are individually expressed in plants and their responses are recorded in parallel. In multiplexing experiments, two or more sensors with non-overlapping excitation and emission spectra are expressed in the same plant. Sensor responses, either recorded in paraplexing or multiplexing experiments over time and through appropriate instruments, such as fluorescence microscopes or plate readers, can be used to create increasingly complex metabolic networks.

A growing list of genetically encoded biosensors helps to shine light on plant metabolism. We reviewed - also for the non-expert - available probes and recent advances in the field:
